I agree with oarframe. Put it in a pocket. It's not a belly chain and you're not Mariah Carey. Wearing a rope or piece of webbing around your torso is stupid, no matter what you've seen people do. Also, consider bright colored webbing - visibility never hurts. I'm guessing you're a first year raft guide so your $200 Green Jacket should have plenty of unused pocket space...
For carabiners get big ass locking pear shaped biners. If you choose auto lock, I recommend no button, just the twist. Auto lockers don't seem to freeze up as easy over time, but you should oil then at least once a year anyway to make sure they work.
